摘要： Exemplary embodiments provide a scalable process for the growth of large scale and uniform III-N nanoneedle arrays with precise control of the position, cross sectional shape and/or dimensions for each nanoneedle. In an exemplary process, a plurality of nanoneedle array can be formed by growing one or more semiconductor material in a plurality of patterned rows of apertures with a predetermined geometry. The plurality of patterned rows of apertures can be formed though a thick selective nanoscale growth mask, which can later be removed to expose the plurality of nanoneedle arrays. The plurality of nanoneedle arrays can be connected top and bottom by a continuous coalesced epitaxial film, which can be used in a planar semiconductor process or be further configured as a photonic crystal to improve the output coupling of nanoscale optoelectronic devices such as LEDs and/or lasers.

摘要： Exemplary embodiments provide semiconductor devices including high-quality (i.e., defect free) group III-N nanowires and uniform group III-N nanowire arrays as well as their scalable processes for manufacturing, where the position, orientation, cross-sectional features, length and the crystallinity of each nanowire can be precisely controlled. A pulsed growth mode can be used to fabricate the disclosed group III-N nanowires and/or nanowire arrays providing a uniform length of about 10 nm to about 1000 microns with constant cross-sectional features including an exemplary diameter of about 10-1000 nm. In addition, high-quality GaN substrate structures can be formed by coalescing the plurality of GaN nanowires and/or nanowire arrays to facilitate the fabrication of visible LEDs and lasers. Furthermore, core-shell nanowire/MQW active structures can be formed by a core-shell growth on the nonpolar sidewalls of each nanowire.

摘要： A method and an apparatus for detecting an abnormal situation are disclosed. The method includes detecting whether a first target exists in an obtained image; recognizing whether the first target holds an object, when the first target exists in the image; obtaining motion information of the object, when the first target holds the object; and determining, based on the motion information of the object, whether the abnormal situation exists.

摘要： In order to help music players without sufficient musical knowledge to adapt original music pieces but still keep the original style, the present invention provides an interactive system and the accompanying method for creating music by substituting audio tracks. The interactive system includes a database of musical elements that comprises tonality, tempo, beat, timbre, texture, chord, and pitch, a database of music that contains multiple original music pieces, and a processor. As a result, players without strong knowledge in music theories can create adapted a music piece that matches the style of the original one.
